DTC P0106: Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance Problem: Description

The manifold absolute pressure sensor detects the intake manifold pressure as a voltage using a built-in sensor. The ECM calculates intake manifold pressure based on this voltage and also calculates the EGR valve and purge VSV opening amount according to changes in the intake manifold pressure.

DTC No.	DTC Detection Condition	Trouble Area
P0106	Intake manifold pressure measured after engine start drops by less than 3 kPa (22.5 mmHg) compared to the intake manifold pressure (atmospheric pressure) measured before engine start (2 trip detection logic).	Intake system Manifold absolute pressure sensor
